MUSICAL WHISTLE.

Application filed February 27, 1924. Serial No. 695,413.

useful Improvements in Musical Whistle/s,

otl which the following is a specification.

This invention relates to improvements in musical instruments and its object is to provide a device particularly adapted to produce various sounds and upon which ditl'eu ent melodies may be played.

Another object of. the invention is to provide a device which may be easily and cheaply stamped from sheet metal and bent to proper form at a minimum of expense.

A further object of the invention is to provide a device wherein the vibration of an elastic member under tension is utilized to produce sound and in which the sound thus produced is made to vary in pitch accordin to the tension of the elastic element when blown upon.

Vith the above and other objects in View, which will appear as the description pro ceeds, the invention consists in the novel constructiom combination and. arrangement of parts which will be fully set forth in the following specification, claimed and illustrated in the accompanying drawing, 11].

which 1 Figure 1 is a perspective view of this musical instrument.

Figure 2 is a side view o l the device showing the elastic element under slight tension.

Figure 3 is a sectional view taken on line 33 of Figure 2.

Figure 4. is a top plan. view ofthe device.

Referring to the drawings in detail, the numeral designates in its entirety the body of this instrument which comprises a pair of plates 11 and 12 oined together at their upper edges at 13 so as to form a chamber or air space 14.

The side edges of the plates 11 and 12 are joined by the tongues 15 and 16, the latter of which is spaced from the joined edges of the plates as clearly shown in Figures 1 and 2 to accommodate the elastic strip 17 and retain it substantially parallel to the upper edge of the instrument,

As illustrated, the end 18 of the strip 17 is bent around the edge of the plate 19. and clamped beneath the tongue 15., while the opposite end of said strip is passed through the opposite side of the device between the joined portion and the tongue 16.

A metallic clip 19 is secured to the outer free end of the strip 17 and serves as a stop to prevent the withdrawal ot the end of the strip into the body 10 as well as a means whereby the strip may be placed under ten sion by manual operation.

Formed in the joining portion 13 of the plates 11 and 12 is an. opening 20 to admit the breath of the user.

In operation, the device is placed so that its closed upper edge rests between the lips of the user and upon exhaling it will be obvious that the elastic strip will be caused to vibrate, thereby producin sound.

3y exerting pull on the elastic strip 17, itis obvious that it will be placed under tension there-by shortening its viln'ations and raising the pitch of the tone produced. in this manner it will be seen that the tones of varyingif pitch may be produced to suit the pleasure of the user, and an operator may .even become suliiciently expert as to be able to play airs and melodies.

\Vhile in the foregoing there has been shown and described the preferred embodiment. of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

1. A musi *al instrument comprising a pair oli plates integrally joined together at their upper edges and being wholly open at one end means connectingthe opposite end edges of the plates, said connecting means having an inlet opening therein,-

a single elastic strip secured between the plates at one side and adapted to pass freely outward between. the plates at the opposite side, substantially parallel to the upper edge of the instrument, and a metal clip of relatively large area secured on the outer end of said strip.

means for retaining said strip 2. A musical instrument comprising a member comprising a thin sheet of material bent on its median line to form a. hollow body open at both ends and having a slit in the bentedge thereof, a tongue on one portion of said body adjacent its bent portion an elastic strip and extending secured beneath said tongue through the device beneath the elongated opening, a handle fixed on the extending end of: said strip and a tongue 10 connecting opposite edges of the device below the elastic strip.

In Witness whereof I have allixed my signature.

\VILLIAM KRAGIEL.
